Impact: optional, useful for debugging Add a new madvice sub command to inject poison for some pages in a process' address space. This is useful for testing the poison page handling. This patch can allow root to tie up large amounts of memory. I got feedback from container developers and they didn't see any problem. v2: Use write flag for get_user_pages to make sure to always get a fresh page v3: Don't request write mapping (Fengguang Wu) v4: Move MADV_* number to avoid conflict with KSM (Hugh Dickins) Signed-off-by: Andi Kleen <ak@linux.intel.com> |
